They don;t need an offering according to their current operations. However if they team up with IMI to commercialize their 3d metal printer, I imagine that might be a new cash drain. However they are expecting aggressive earnings time table, so how much that will mitigate dilution is unknown yet, my guess is they will dilute a small amount, not very much though. Demand is certainly high I think they could get an aggressive price on a small offering a well.
Good question- According to their Q1 statement filed last month, management stated: "Based on the funds we have as of May 15, 2013 and the revenues we expect to receive under our consulting agreements, we believe that we will have sufficient funds to pay our administrative and other operating expenses for the balance of 2013"
No guarantee they won't do an offering though I guess- they may need to so they can launch PrintRite3D?
